Bug 1100999

Description of problem:

When copying a thin provision nfs template to iscsi domain,the image group that is created on the block domain consists of one raw preallocated volume disk.
on NFS domain the template consists of raw sparse logical volume.

from terminal vdsClient:

on NFS->

[root@camel-vdsb data-center]# vdsClient -s 0 getVolumeInfo $sduuid $spuuid $imuuid `vdsClient -s 0 getVolumesList $sduuid $spuuid $imuuid`
	status = OK
	domain = 1b2dcee9-bcb1-4b80-8e7f-eaa4fc659c1a
	capacity = 4294967296
	voltype = SHARED
	description = Active VM
	parent = 00000000-0000-0000-0000-000000000000
	format = RAW
	image = 4158dea2-9c92-4167-a65f-bde633364745
	uuid = ab488d9f-fa43-4b67-bb1a-7e0405c3e652
	disktype = 2
	legality = LEGAL
	mtime = 1401007275

	truesize = 24576
	type = SPARSE
	children = []
	pool = 
	ctime = 1401007275

on ISCSI->

[root@camel-vdsb data-center]# vdsClient -s 0 getVolumeInfo $sduuid $spuuid $imuuid `vdsClient -s 0 getVolumesList $sduuid $spuuid $imuuid`
	status = OK

How reproducible:
100%

Steps to Reproduce:
Setup:have a shared dc with two domains(one nfs,one iscsi)

1.create vm+thin nfs disk-> create a template from this disk
2.copy template to iscsi domain

Actual results:
the web admin ui reports of a thin provision template(see image)

Expected results:
we should see both,or whatever makes sense
